Surrey 4 (1988–1993) The original Surrey 4 was tier 11 league with promotion to
Surrey 3 and relegation to
Surrey 5, until that division was cancelled at the end of the 1991–92 season.
Surrey 4 (1993–1996) The creation of
National 5 South meant that Surrey 4 dropped from a tier 11 league to a tier 12 league for the years that National 5 South was active. Promotion was to
Surrey 3 and there was no relegation as Surrey 4 was at the lowest level of the league structure.
Surrey 4 (1996–2000) The cancellation of
National 5 South at the end of the 1995–96 season meant that Surrey 4 reverted to being a tier 11 league. Promotion continued to
Surrey 3 and there was no relegation. Surrey 4 was cancelled at the end of the 1999–00 season, with the majority of teams transferring to Surrey 3 or dropping out of the league system.
Surrey 4 (2005–2009) Surrey 4 was reintroduced as a tier 12 league for the 2005–06 season. Promotion was to
Surrey 3 and, as the division was at the lowest level of the English league system, there was no relegation.
Surrey 4 (2009–present) Surrey 4 remained a tier 12 league despite national restructuring by the
RFU. Promotion continued to
Surrey 3 and there was no relegation. ==Number of league titles==
